Title: Process for producing pyrogenic titanium dioxide pigment
IPC: C01G23/07
Filed: 1969-03-01
Abstract: In a process for producing finely divided TiO 2 by reacting TiCl 4 with O 2 in the presence of hot CO combustion gases, the gases are fed through a concentric inlet arrangement comprising a central spindle with an enlarged end section and surrounded by at least one annular inlet, the spindle rotating at such a speed that the centripetal acceleration of a point on the widest part of the end section is at least 50g. CO combustion may take place in the reaction zone or in a preliminary zone. In Fig. 1, rotating body 7 is cooled by cooling medium fed in at 11 and out at 15. TiCl 4 is introduced into space 22, O 2 into 21, and CO into 20. In Figs 2-4 (not shown), end section 13 is replaced by a disc and shaft 12 extends below the end of tube 3. The disc may have strips 24 on its top and bottom faces. In Fig. 5, O 2 and CO from 21 and 22 form an auxiliary flame in zone 27. TiCl 4 is fed through 22 into space 29, then through orifices 30 into the flame. Cool gas, e.g. reaction waste gas, is fed through pipe 31 and enters reaction zone 2 via annular gap 34. A gas may be fed through tangential pipes 35 to keep the walls free from deposits. In Fig. 6, a mixture of CO and O 2 is fed through 38 and burns in zone 41. TiCl 4 is fed through shaft 12 and orifices 40 into the flame. In Fig. 7 (not shown), end section 13 has hollow cylinder 25 attached. Cool gas is introduced through tube 31 as in Fig. 5. The TiCl 4 may contain AlCl 3 or SiCl 4 . In examples, TiCl 4 is preheated to 300 C., O 2 to 250 C., and the CO or CO/O 2 are used at room temperature. Dimensions of all the parts and rotation rates are given.

Patent ES-458539-A1 (ES)
Title: Method and apparatus for cleaning a filter bed
IPC: B01D46/34
Filed: 1977-05-06
Abstract: The invention concerns the cleaning of the granulate filter bed material of a gas filter. The granulate material is contained in the spaces between two or more gas-permeable walls. The walls are designed as vertical tubes which may be cylindrical or consist of two cones with their bases together. The crude gas passes transversely through these walls from an outer chamber into an inner chamber from where it is led away as purified gas. A transfer pipe runs from the bottom of the filter bed to the top. A current of conveyor air is forced through the transfer pipe so that it carries the granulate material from the bottom to the top of the filter bed. At the top of the filter bed the conveyor air escapes through a gas-permeable hood while the granulate material falls into the space(s) between the gas-permeable walls, passes down between the walls and eventually reaches the bottom of the filter bed again. This circulation of the filter bed material by means of the conveyor gas passing through the transfer pipe can take place during a separate cleaning phase or at the same time as filtration. Provision is also made for passing blasts for scavenging air through the filter bed in the opposite direction to that of the crude gas flow in order to remove filter cake adhering to the outside surface of the outer gas-permeable wall.
